Captain Christopher Pike

One who is caught off guard, and goes into shock when asked a question under pressure and just freezes up staring straight ahead. Refers to specially-seated, paralyzed character in an early episode of Star Trek who was motionless, jaw slacked and could only communicate via flashing lights with a yes or no.
Can be contracted to Piked-up or Pike with a capital P out of respect.

All kidding aside, Captain Christopher Pike is a fictional character in the Star Trek universe. According to the original series lore, Pike commanded the U.S.S. Enterprise NCC-1701 from 2250-55, and again from 2258-63. When Pike's second tour of duty on the Enterprise was complete, the ship returned to Earth, and Pike was relieved of command and promoted to fleet captain. Command was then transfered to James T. Kirk. Three years after his promotion, Pike was involved in a radiation accident that left him burned, paralyzed, mute, and confined to a life-support wheelchair.

Pike is also featured in J.J. Abrams' 2009 reboot of Star Trek. He is first seen breaking up a bar fight in Iowa between 25-year-old James T. Kirk and some starfleet cadets under his supervision. Pike then plays mentor to Kirk, urging him to join starfleet and follow in the footsteps of his father, George Kirk. Pike is also seen as Captain of the Enterprise, although much more briefly than in the original series timeline (it is established that the events of the reboot are in fact an alternate reality influenced by the Nero, the film's villain, thus explaining the contradictions between the original series and the reboot).
